Thyroid and salivary gland are amongst the most common sites subjected to fine needle aspiration cytology (FNAC) due to easy accessibility of these sites along with high diagnostic accuracy of FNAC. The performance of FNAC can be increased with the use of ultrasonographic guidance and rapid on-site evaluation. Cell block along with immunochemistry and other ancillary techniques further helps in clinching the correct diagnosis in certain diagnostically challenging cases. Core needle biopsy (CNB) is proposed to have a better diagnostic accuracy in certain situations. However, CNB has no definite role as an upfront first-line diagnostic technique for thyroid or salivary gland lesions. We describe role of FNAC and CNB in thyroid and salivary gland lesions with detailed discussion of advantages and disadvantages of both these techniques.
甲状腺和唾液腺是最常接受细针穿刺细胞学检查（FNAC）的部位，因为这些部位易于触及，且FNAC具有较高的诊断准确性。使用超声引导和快速现场评估可提高FNAC的性能。细胞块联合免疫化学及其他辅助技术在某些诊断具有挑战性的病例中进一步有助于做出正确诊断。在某些情况下，粗针活检（CNB）被认为具有更好的诊断准确性。然而，CNB作为甲状腺或唾液腺病变的一线初始诊断技术并无明确作用。我们描述了FNAC和CNB在甲状腺和唾液腺病变中的作用，并详细讨论了这两种技术的优缺点。
